## 1. Role

### JKKKisnUwHmdkAddCC.execKikiOptDsl()

This method performs the core business operation of **cancelling machine option service contracts** (機器オプションサービス契約解約) in a Fujitsu telecom billing/order fulfillment system. It is the central dispatch method for the "DSL" (likely "Data Service Line" or similar) cancellation flow, iteratively processing each machine option service (equipment-attached service) returned from a prior list inquiry.

The method implements a **routing/dispatch pattern** combined with **delegation**: it queries a list of machine option service contracts via `execEKK2811B504`, then for each valid contract (excluding those already in cancellation status "910"), it performs multi-step processing. First, it fetches the service agreement details via EKK2801A010 to determine penalty applicability, then retrieves the parent service agreement via EKK0081A010 for billing date comparison, and performs the contract-level inquiry via `execEKK2811A010` to extract charge start/end dates. It then calculates and adjusts the service charge end date and start date based on whether the contract is being cancelled on the same month as its charge start (sliding logic), before finally executing the cancellation (EKK2811C140) and, if this is a registration-level cancellation (func_code = "1"), the cancellation confirmation (EKK2811C150).

Its role in the larger system is as a **shared component method** called by `execKikiDsl()` — the screen-level CBS entry point. This separation allows the same cancellation logic to be reused across different service types (FTTH DSL, etc.) by accepting the contract number via `svc_kei_no`.

| 1 | CALL | `ekk2811b504cbsMsg = execEKK2811B504(handle, scCall, param, dataMapKey, outList.getString("kktk_svc_kei_no"))` // Machine option service contract list inquiry (機器オプションサービス契約一覧照会 - combined search) |

**Block 3** — IF `(result null or empty check)` (L1919)

Guard clause: if no machine option service contracts were returned, the entire method body is skipped (no cancellation needed).

| # | Type | Code |
|---|------|------|
| 1 | IF | `ekk2811b504cbsMsg != null && ekk2811b504cbsMsg.length > 0` // Check if machine option service contract list has records |

| 2 | CALL | `ekk2801a010Msg_out = callSC(handle, scCall, param, dataMapKey, ekk2801a010IN).getCAANMsgList(...)[0]` // S-I/F call to EKK2801A010 - machine option service agreement inquiry (機器オプションサービス照会) |
| 3 | SET | `KKOP_SVC_KEI_NO` = `ekk2811b504cbsMsg[i].getString(...)` // Machine option service contract number (機器オプションサービス契約番号) |

**Block 9** — SET + CALL `(parent service agreement inquiry — v8.02.00 addition)` (L1953-1968)

Fetch the parent service agreement to obtain the service charge start date for sliding date comparison. This is a v8.02.00 addition (v8.02.00 追加開始). EKK0081A010 is called with func_code "2" (detailed inquiry mode).

| # | Type | Code |

**Block 11** — SET `(charge end date calculation)` (L1998)

Calculate the service charge end date as one day before the cancellation date (取消日の前日を設定).

| # | Type | Code |
|---|------|------|
| 1 | SET | `svcChrgEndYmd = JPCDateUtil.addDay(unyobi, -1)` // Service charge end = cancellation date minus 1 day |

**Block 12** — IF `(charge start date not empty check)` (L2000)

Determine whether sliding of charge start dates is needed by comparing dates.

| # | Type | Code |
|---|------|------|
| 1 | IF | `!" ".equals(svcChrgStartYmd)` // Process only if service charge start date is not empty |

**Block 13** — IF `[svcChrgEndYmd < svcSvcChrgStaYmd]` `(no sliding case)` (L2004)

If the calculated charge end date is before the parent service charge start date, this is a same-item cancel request (スライドしない - no sliding). The dates remain unchanged.

| # | Type | Code |
|---|------|------|
| 1 | IF | `0 > svcChrgEndYmd.compareTo(svcSvcChrgStaYmd)` // Charge end date < parent service charge start date |
| 2 | COMMENT | // スライドしない（キャンセル依頼の同一項目）- No sliding: cancel request for same item |

**Block 14** — IF `[svcChrgEndYmd < svcChrgStartYmd]` `(sliding case)` (L2010)

If the calculated charge end date is before the current service charge start date, sliding is needed (スライドする). The charge start dates are adjusted to the service start date.

| # | Type | Code |
|---|------|------|
| 1 | IF | `0 > svcChrgEndYmd.compareTo(svcChrgStartYmd)` // Charge end date < machine option charge start date |
| 2 | SET | `svcChrgStartYmd = svcStaYmd` // Set service charge start date to service start date |
| 3 | SET | `planChrgStartYmd = svcStaYmd` // Set plan charge start date to service start date |

**Block 15** — SET `(prepare cancellation input data)` (L2017-2031)

Build the input object array for the cancellation CBS (EKK2811C140). This includes the cancellation date, charge end date, penalty occurrence status from EKK2801A010, function code, iteration index, and the previous update timestamp for optimistic concurrency control.

| # | Type | Code |
|---|------|------|
| 1 | SET | `EKK2811C140IN = {TEMPLATEID, TEMPLATE_ID_EKK2811C140, FUNC_CODE, ccMsg.get("func_code"), KKOP_SVC_KEI_NO, kkopSvckeiNo, MSKM_DTL_NO, ccMsg.get("mskmDtlNo"), RSV_TSTA_KIBO_YMD, setNull(), SVC_ENDYMD, unyobi, SVC_CHRG_ENDYMD, svcChrgEndYmd, SVC_DLRE_CD, setNull(), SVC_DLRE_MEMO, setNull(), PNLTY_HASSEI_CD, ekk2801a010Msg_out.getString(PNLTY_HASSEI_UM), IDO_DIV, ccMsg.get("ido_div"), UPD_DTM_BF, ekk2811a010cbsMsg.getString(LAST_UPD_DTM), SVC_KEI_NO, svc_kei_no}` // Build EKK2811C140 cancellation input |

**Block 16** — CALL + SET `(execute cancellation)` (L2034-2037)

Execute the machine option service contract cancellation and update the timestamp.

| # | Type | Code |
|---|------|------|
| 1 | CALL | `ekk2811c140Msg_out = callSC(handle, scCall, param, dataMapKey, ekk2811c140IN)` // S-I/F call to EKK2811C140 - machine option service contract cancellation (機器オプションサービス契約解約) |

**Block 17** — IF `[func_code = "1"]` `(cancellation confirmation)` (L2039)

Conditional confirmation: only when func_code equals "1" (registration/execution mode, 登録のみ実施), the cancellation confirmation step is executed. This ensures cancellations are confirmed in the normal registration flow but not in inquiry-only flows.

| # | Type | Code |
|---|------|------|
| 1 | IF | `"1".equals(ccMsg.get("func_code"))` // Only for registration (本登録時のみ実施) |

**Block 18** — SET `(prepare confirmation input data)` (L2042-2058)

Build the input object array for the cancellation confirmation CBS (EKK2811C150). This includes the service/plan charge end dates, service/delivery reasons, DSL charge flag, and the previous update timestamp.

| # | Type | Code |
|---|------|------|
| 1 | SET | `EKK2811C150IN = {TEMPLATEID, TEMPLATE_ID_EKK2811C150, FUNC_CODE, ccMsg.get("func_code"), KKOP_SVC_KEI_NO, kkopSvckeiNo, SVC_ENDYMD, unyobi, SVC_CHRG_ENDYMD, svcChrgEndYmd, SVC_CHRG_STAYMD, svcChrgStartYmd, PLAN_CHRG_STAYMD, planChrgStartYmd, PLAN_ENDYMD, unyobi, PLAN_CHRG_ENDYMD, svcChrgEndYmd, SVC_DLRE_CD="01", SVC_DLRE_MEMO="", DSL_JI_CHRG="1", UPD_DTM_BF, getSvcUpDtm(param)}` // Build EKK2811C150 confirmation input. PLAN_CHRG_STAYMD uses planChrgStartYmd (v8.02.00 change - previously used svcChrgStartYmd) |

**Block 19** — CALL + SET `(execute confirmation)` (L2061-2065)

Execute the cancellation confirmation and update the timestamp. Note: the update timestamp is read from `EKK0341C350CBSMsg.UPD_DTM` (possibly a template ID reference).

| # | Type | Code |
|---|------|------|
| 1 | CALL | `ekk2811c150Msg_out = callSC(handle, scCall, param, dataMapKey, ekk2811c150IN)` // S-I/F call to EKK2811C150 - cancellation confirmation (機器オプションサービス契約解約確定) |
